Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SR
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SR is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 400mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SR
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 400 mm stroke with a 1/8" port and M6x1.0 male rod thread. The rolled stainless barrel and rod naturally resist mild corrosion, outperforming painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb impact at the stroke ends, and the built-in piston magnet (-S) directly supports CMSG, DMSG, or EMSG reed and electronic switches.
For practical sizing, plan for roughly 60 N of usable work at 0.5 MPa, which translates to lifting about 5.1 kg vertically with a safe 2:1 margin. The R back cover provides an axial-in port orientation for tight layouts. Because this bore falls within the Ø8-Ø25 range, it uses the ISO 6432 mounting interface, dropping smoothly into standard mini-cylinder brackets and clevises.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SR Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using 100.5 N of thrust, with the 400 mm stroke fully clearing the belt for unobstructed product flow.
Lab Sample Tray Shuttle
Moves sample trays between testing stations in humid environments, relying on the stainless-steel barrel to resist mild corrosion from daily washdowns.
Parts Ejector Drop
Extends 400 mm to eject machined plastic parts from a fixture, using the fixed TPU bumper pads to soften the stopping impact at the end of the stroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SR the Right Cylinder?
When sizing this 16 mm bore, the smaller Ø12 generates 56.5 N push while the larger Ø20 yields 157.0 N at 0.5 MPa, giving you clear scaling if the 100.5 N output is borderline. The 400 mm stroke is well within the 500 mm maximum standard stroke for this bore, but at this length you must carefully manage side loading to prevent rod bending and premature seal wear. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion blocks.
Remember that a plain double-acting cylinder drifts when air is removed or the valve is centered; the TPU bumpers only decelerate the end of travel and do not act as a brake. If your application requires vertical load holding on air loss, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MI16-20 Stainless Steel Mini Cylinder MI16X400SR FAQ
This 16 mm bore cylinder uses a 1/8" port and an M6x1.0 male rod thread. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, with a theoretical maximum force of 20.5 kgf at 1.0 MPa.
The -S suffix indicates a built-in magnet for CMSG, DMSG, and EMSG switches. It cannot hold a vertical load on air loss; the piston drifts, so you need an external pilot check valve or rod lock for holding. It uses the ISO 6432 mounting interface and fixed TPU bumper pads for end-of-stroke deceleration.
